How to Clear DNS Cache for beginners
Everytime you surf the NET, your operating system will directly store all of your DNS information. This could also lead to problems, such as: “DNS unable to resolve, error loading pages and server timeout.” But, don’t just hold your breath and think its gone after reboot.
How to solve this?
As an IT geek, you may use this tutorial for cleaning / flushing your ‘DNS cache’. So, don’t get all excited if you are just a beginner. This tutorial was also analyzed and tested by idiot – proof – users.
1.] First of all, you must check your system ‘Services’ for this process: ‘DNS Client’. If this process is disabled or set to manual, then you will have to alter / reconfigure it to ‘Automatic’. Without this process, you cannot flush your ‘DNS Cache’.
Click Start >> Right Click: My Computer >> Manage >> Services and Applications >> Services >> Search for this process: DNS Client.
2.] At this stage, you will need to click ‘Start >> Run >> Type: CMD >> Type: ipconfig /flushdns’
Vista Operating Systems
1.] Click on your Vista ‘Start Logo’. Its right infront of your desktop!
2.] Click on ‘All Programs >> Accessories >> Right –click on Command Prompt (CMD) >> Select: “Run As Administrator…”
3.] In Command Windows, you will need to type in this script: ‘ipconfig / flushdns’.
4.] You are done!
Warning: this last guide is only for Windows XP Home / Pro & Vista only! If you want to use this option for Windows 7, please skip this paragraph and look for it somewhere else…
Alternative: if you really want to block Windows XP / Vista from negative entries and errors, you can alter these parameters. However, I would recommend you to create a backup before usage or touching your registry.
1.] Click ‘Start >> Run >> Type: Regedit’.
2.] Navigate yourself to the ‘Parameter’ directory.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters
3.] Create a new ‘DWORD’ value and called it: ‘NegativeCacheTime’.
4.] Give your value a Zero and apply the changes.
Notes: for Windows Vista, there is a longer route. But, it will work if you carefully add these values.
a.] Right –click: ‘New >> DWORD (32-bit) Value.”
b.] Name your new value as: “CacheHashTableBucketSize” and give it a value of 1 (Enable).
c.] Repeat ‘Step 3 – NegativeCacheTime’ and give it a value of 0 (Zero).
NegativeCacheTime = 0
5.] Reboot your computer and do whatever you want. It’s your computer!
